If you have a single building that is a high-rise, then the entire building is 
a high-rise.  

 

On another note, I’m not sure how a 9 story building isn’t a high rise unless 
it is less than 8’-4” between floors.

Subject: High Rise and Non-High Rise Standpipes

 

I've got a building that is two towers with a parking garage in between. One 
tower is 11 floors and is a high rise, with two standpipes. The other tower is 
9 floors and isn't a high rise, with three standpipes. The AHJ has said that 
because the towers and garage are all connected, the tower that isn't a high 
rise is considered a high rise with respect to standpipe calculations. I had 
originally considered my calc to be 750 gpm for the two standpipes in the high 
rise, them being automatic wet, and 1000 gpm for the three in the non-high 
rise, them being manual wet. Does it make sense that the AHJ has said it is one 
building with 5 standpipes, and to do a 1000 gpm calc with the two standpipes 
in the high rise and one in the non-high rise (the fire pump is in the non-high 
rise)?
